This is great! so in the perl script you were just using the standard memcache
libraries? Nice!<br>

Are those lookups independent of SIP signalling? I know memcache supports
well over 10K/sec.. Just curious if you'll get that performance with the perl
libs in the middle.<br>

<p>I'm doing something similar, being that I need a lookup per INVITE. Bogdan's
recommendation for me was to use the memcaching functions in 1.5:<o:p></o:p></p>

<p style='margin-bottom:12.0pt'>Hi all, I'm trying to figure out if we can use
or add functionalities to dynamic routing module to do "incoming
routing" based on callee destination ($ru) per user<br>
The idea is to have inbound rules per user (username/domain or user aliases
i.e. numbers ) <br>
Each user will set their incoming rules, i.e. First rule ring my numbers and
username (lookup registered devices) for 15 seconds, then call my cellphone for
10 second, then call<br clear=all>
home number for 20 seconds and then call my voicemail, each step may ring on
more than one devices at the same time, it's a mix of serial and parallel
forking. Condition to do next step is if get 4XX errors (not found, busy, etc)<br>
We can add also time conditions and black/white list. <br>
<br>
I did it using custom avp_db_query but will be nice have rules on memory
without querying tables every time.<br>
<br>
I'll be waiting for your suggestions<br>
<br>
Best,<br>
